The Partnership evaluates segment performance on the basis of operating income, which is derived by subtracting cost of products sold, operating expenses, selling, general and administrative expenses, and depreciation and amortization expense from revenues. The following tables furnished below set forth the Partnership's operating results by segment for each quarter of the year ended December 31, 2012.

The Partnership acquired certain specialty lubricant product packaging assets from Martin Resource Management in October 2012. The acquisitions of these assets were considered a transfer of net assets between entities under common control. The acquisition of the assets was recorded at amounts based on the historical carrying value of the assets at that date, and we have retrospectively updated our quarterly segment financial information below to reflect the effects on operating results attributable to the activities of the assets as if we owned the assets from January 1, 2012 through September 30, 2012. The historical results of these assets are included in the terminalling and storage segment information below.

Included with this press release is the Partnership's quarterly financial information for the year ended December 31, 2012 by reportable business segment.
